Silicone Valley 

Nickname for the San Fernando Valley in California, known for having a lot of porn studios.

I moved to the Silicone Valley with my rubber tits to pursue a career as a porn star. After starring in over 200 creampie gangbangs, I upgraded my tits and ass from rubber to Silicone. I get even more, and higher quality, dicks in my pussy.

Silicone Valley 

The cleavage that is a result of breast implants and poor choices of blouses.

Her cleavage was referred to as her ‘Silicone Valley’... because of its ‘inception’ created after breast augmentation.
